Sep. 11, 2013 ? Ducks and gulls are the natural hosts of influenza A virus. Ragnhild T?nnessen's PhD research project has characterised influenza A viruses in gulls and ducks in Norway. Her discoveries may lead to a better understanding of the epidemiology and host adaptation of influenza A virus.
Wild birds, particularly ducks and gulls, are the natural hosts for influenza A viruses which can cause disease in animals and humans. Influenza A viruses can be divided into subtypes, of which the majority have been found in wild birds. Most subtypes of influenza A virus cause subclinical infections in wild birds. Infections in domestic chickens most commonly result in mild disease. In rare cases, if introduced from wild birds to poultry, some viruses of the H5 and H7 subtypes mutate and become highly pathogenic. One example of this is the highly pathogenic H5N1 virus in Southeast Asia known to cause ?bird flu?.
